I’ve been using my Edge 11 on my NEQ6 for 10 years without a hitch, mostly for visual and planetary imaging.
It’s a great visual scope...and has a nice flat field with even the widest eyepieces, and is well corrected for full frame cameras. I don’t doubt the 9.25 is too.
Like Andrew says, the difference will be whether you’re gunning for small objects or larger ones. Well, I’m reality they’re all small if you’re using that kind of focal length
but your intent will determine the best match.
